1986 Pontiac Fiero 6 cyl Two Wheel Drive Manual
I replaced the motor in my Fiero and have not got it to fire. There is good spark to each cylinder. There is 45 PSI fuel pressure to the fuel rail. The replacment motor is an exact copy of original motor. Estimating motor to have 120,000 miles on it and has not been in a running vehicle for quite a few years. Everything seems to be in good order, just won't start. I do not believe the injectors are spraying fuel because plugs are always dry as a bone. To elimate bad injectors, I swithced out injectors from original motor. I have also swapped out a buch of sensors. Still nothing.
I am wondering if I have a wiring issue because the wiring harness on this motor I picked up was cut, rather than unplugged. So, I simply spliced the harnesses together with crimp type connectors. Every wire matched so I did not think it would be a problem. I am now wondering if I should solder the wires instead. I have also added a bunch of grounds in random places. Maybe the ECM?
The motor itself seems to have good compression and turns over quite nicely.
I am baffled on this one. I am extremely appreciative of any help I can get with this. Thanks guys.
have the same problem?
